A Framework to Ensure Quality of Service with New Trail and Security in Networks

The authors present a method to find another path, after link failures, from a source node to a destination node, before the interior gateway protocol (e.g., OSPF or IS-IS) has had a chance to reconverge in response to the failure. The target application is a small (up to tens of nodes) regional access sub-network of a service providing networks, which is typical access scale encountered for the practice. They can illustrate the method and prove that it will found in a path if one exists.
